Unable to process refund from backend with Stripe

Hi,

as specified in Stripe plugin description
" * Create manual payments and process refunds from your Shopware Backend"

There should be a way to process Stripe refund directly from Shopware backend but I cannot a find to do so. Because with paypal there is a new tab in the order screen, but with Stripe nothing seems to work and also if I change the order status to refund, nothing happens.

Anyone faced the same issue?
